/**

> Creates an item for QTreeWidget.

* **This class is a JS wrapper around Qt's [QTreeWidgetItem class](https://doc.qt.io/qt-5/qtreewidgetitem.html)**

### Example

```javascript

const { QMainWindow, QTreeWidgetItem, QTreeWidget } = require("@nodegui/nodegui");

const win = new QMainWindow();
const tree = new QTreeWidget();

const item1 = new QTreeWidgetItem();
item1.setText(0, `item-1`);
const item2 = new QTreeWidgetItem();
item2.setText(0, `item-2`);
const item3 = new QTreeWidgetItem();
item3.setText(0, `item-3`);

tree.addTopLevelItem(item1);
tree.addTopLevelItem(item2);
tree.addTopLevelItem(item3);

// Add children to item1
const c1item1 = new QTreeWidgetItem(item1);
c1item1.setText(0, `c1item1`);
const c1item2 = new QTreeWidgetItem(item1);
c1item2.setText(0, `c1item1`);

win.setCentralWidget(tree);
win.show();
(global as any).win = win;

```
